I set up an electrolysis experiment to show my kids and wanted to explain to them what is happening.
My setup has a penny as the anode and graphite for the cathode. The solution is water with baking soda mixed in.
I see bubbles at each of the electrodes which I assume are hydrogen and oxygen bubbling out. I also see some cloudy substance coming off the penny, which I assume is some sort of copper compound, but I'm not sure.
Can someone help me figure out what's going on in the setup at the two electrodes?
Edit : corrected the electrode descriptions. I earlier stated penny as the cathode and graphite as the anode.
